/OUT:filename
This option overrides the default name and location of the program that the linker creates.
By default, the linker forms the file name using the base name of the first .obj file specified and the appropriate extension (.exe or .dll).
The Output File Name option controls the default base name for a .map file or import library. For details, see Generate Mapfile (/MAP) and /IMPLIB.
